How save custom fields in joomla user with override

Hi,
I created a registration form with multiple field (name, username, city, email, telephone, ecc.)
I try to save a custom field (citta) in joomla user with override but without result. The field citta remains empty
- I create a new field in "users->add field" (photo 1)
- in "Save user-> data override" i put "field_3:{data:citta}" (photo 2)
- in "save data" i create data override "value" and "field_id" (photo2)
I also attach the photo 3 with "area fields label: città"

I searched for different solutions on the forum but none was useful. you can help me?

Don't save random new fields to the users table. Use the "custom fields" action, after creating a new custom field in Joomla.

I try to put the data in "custom filed" action but I don't have results.
I’m at the beginning, can you explain it better please?

Thanks for your help

customfieldname:{data:formfieldname}
​
And make sure you've created the custom field first. Google Joomla Custom User Fields

There is something wrong..
I create custom user fields as you can see from the images I uploaded yesterday to you.
The name of new custom field is "citta"; type:text; ID:3
In form design the name of the field are: "citta"
In setup of form I put in "save custom fields" this:
Item id provider: 3
Fields:value list (customfieldname:{data:formfieldname}): citta:{data:citta}

it's correct?

In setup setting, do i have to enter other data? for example.. in "save user" or in "save data"?

Thank you

You didn't literally write (customfieldname:{data:formfieldname}): citta:{data:citta} did you? Just use
​

citta:{data:citta}

And the item ID provider should be {user:id} not 3

I try with
Item ID provider: {user:id}
fields: citta:{data:citta}
​
but in fields "citta" in table joomla "name_users" I don't see anything yet.
​
In the setup form i put "save custom field" after "save user" is correct?
The Joomla custom user field must have any particular settings?
​
Thank you

If you're saving a new user, then you would need to instead of {user:id} use {var:joomla_user#.id} replacing the # with the number in the black label of your save user action.

Hi,
I try but the result is the same.
The black label of my save user is: joomla_user3
​
item ID provider: {var:joomla_user3.id}
fields value list: citta:{data:citta}
​
I try I tried to fill out the registration form but I don't see anything in label "citta" in table joomla users.
​
if this data is correct, where could the error be?
​
I only see these compiled fields name, username, password, email.
​

Thanks for you patience

It doesn't go in the Joomla users table buddy it goes in fields_values

Hi,
I need the value "data" to go in the joomla users table.

No, you just think you do. Don't add columns to core Joomla tables.
